'H EMM ER FOR SEWING- MACHINES.

SPECIFICATION forming part of Letters Patent No. 264,845, dated September 26, 1882.

Application filed December 5, 1881. (No model.) i

To all whom it may concern:

Be it known that I, MILTON I. BAIRD, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hemmers; and I do hereby declare thefollowing to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention has for its object to furnish a new and improved hemming and binding attachment for sewing-machines.

It consists in two scrolls, one placed above the other, a guide'lip, side guides, and other mechanism, all combined and arranged to operate as hereinafter fully set forth.

In the drawings, Figure 1 is a perspective, Figs. 2 and 3 are elevations taken from opposite sides, Fig. etis an elevation of the exit end, and Fig. 5 is an elevation of the receiving or entrance end, of a device constructed according to my invention. Fig. 6 shows the blank from which the device is formed. Fig. 7 is a plan of the scroll, made on an enlarged scale. Fig. 8 is a section on line as a, Fig. 2;

and Fig. 9 shows a plan and a side view of the slotted plate for holding the hemmer and binder.

(t is the holder to which the hemmer and binder is fastened. It is provided with a slot, at, through which passes the thumb-screw by which it is fastened to the cloth-plate of the sewing-machine. Ithas its other end stamped upward, so as to provide a raised portion or platform, ed, on which the hemmer is placed. The platform a has its outer edge bent downward so as to form a short lip or foot, aflwhich rests on the cloth-plate of the machine and gives firmness to the position of the platform. ln'constructin g the foot a and platform a they are formed and arranged so as to hold the hemmer and binder in an inclined position, with the exit end lower and close to the clothplate. I 'cut from the middle portion of the platform a a rectangular flap, a, (one side of which remains attached,) which I bend over toward the shank a of the holder and down to a level with the said platform. The free end of this flap is bent under to form a hooks haped folder, a, which nearly touches the upper surface of the holder, as shown in Figs. 4 and 5, space being left below it to permit the passage of the fabric. Itserves as asupport for the ends of the bed-plate of the scrolls. The piece of goods is passed under the hemmer and its edge is folded by the folder c, and it is then conveyed under the main scam, and is sewed to the under side thereof at the same piping, and lace are sewed to the upper side.

That my invention may be better understood, I will describe the form and method of folding the blanks from which'the hemmerscrolls are made. In the drawings, Fig. 6 shows this blank, which is designated by the letter I). The blank b is cut from a sheet of suitable metal in the irregular form shown. \Vhen thus out there is presented the large wing b,

oval projections b b the projection I) being formed a little shorter than b which, when folded together and bent upward, make the lip or flange at the entrance of the hemmerscroll; the nearly-rectangular projection b", which extends outward from the under side of the entrance to the piping-scroll; a side notch, b which forms an opening for the passageof piping orother like finishing material; a tapering-proj ection, b, which projects outward from the under side of the exit end of the pipingscroll, and which is partialiycut off by a cross slit, b cut from the inner side thereof; a transverse tongue, b, provided with an eye or opening, b, all arranged around the edge of said blank. in the positions shown. The notch b and the slit b are cut from opposite directions, and have their inner ends about on the same line, yy. The blank thus formed is folded into the scrolls as follows: Let line y y be drawn across the blank from the inner edge of the projection I1 to a point near the middleof the projection b another line, 2 a, be drawn from the middle point between the semi-oval projections b b to the inner end of the slot bethe transverse tongue b, and-a third line, z 2, be drawn from near the outer end of the slot;

which becomes the bed-plate; the two semitime and by the same operation that the braid,

tween the projection b andthe fast end of 10 5 three sections nearly equal in width, and havingacorresponding taperfrom end toend. The first or outer section, 0, is bentdownward and under the second or middle section,c. A sufficientspaee islet't between these two sections for the passage of the fabrics. When the outer section is thus bent it, with the second section, forms what I call the piping or under scroll, A. The notch 12 becomes an opening through to the under side of the pipingscroll, as shown in Fig. 2. In bending the first section, 0, the crease on the line y y does not extend through the projection I), but reaches only to theinnerend of slit b When the section is bent down as described that portion of the extension I) marked turns outward, and is afterward curved upward to form anearly-vertical side guide, as shown in Fig. 4.. The middle section, 0, is bent upward on the'line z z and over the third section,

25 0 It is pressed firmly against the section 0 so that the two together make a strong partition or central guide, B, between the piping scroll and the hemmer-scroll, hereinafter described. When folded thus the two semi-oval 0 projections come together, and the two plates or thicknesses of metal are bent upward to or nearly to a vertical position, and compose the lip or guide 0 at the entrance of the hemmerscroll. The narrow wing 0 of the extension 1) laps over and close to the inner end of the transverse tongue 11 In ordinary hemmers the lip 0 placed at the entrance of the scroll, is very light, and is easily and soon bentdown by the; fabrics which are passed over it. It

0 has been impossible to make it strong enough in any oftheordinaryhemmers tobear thestrain made upon it. In my device I have provided a lip made double by the manner of folding of the blank,and thereby made strong enough 5 to endure any strain that may be put upon it. ""Ihe projection b is out a little shorter than the projection If, so that when the two are bent upward to a Vertical position their edges will be flush. The folded sections 0 c 0 and o the wing b are now rolled together, so that the said wing will be formed into a tapering tubula r-shaped hemtner-scroll, D, arranged above the pi ping-scroll A and separated from the latter by the intermediate guide or partition, B.

5 The wing 12 passes close to but does not touch the edge of the partition B; but space enough is left to afford facilities for manipulating the goods. The end of the wing 12 passes under and close to the under sideot' thepiping-soroll, and is carried outward horizontally and becomes a bed-plate for the scrolls, as shown at E, Figs. 4 and 5, while the extension I) is below and reaches beyond the end of the extension 1). When thus folded it will be seen that the section 0 is the bottom or under side of the hemmer-scroll D, and that the section cis the bottom of the piping-scroll A. It will be seen, also, that the end of the section 0 to which the transverse tongue b is attached, and the end of the section b, and the end of the ing steps from the hem mer to the cloth-plate of the machine. By this arrangement the several articles of goods which are being sewed together are carried from the hemmer to the. needle Without being wrinkled or otherwise disarranged. In order to make this descent more gradual than it otherwise would be, it will be seen that the portion 0 of the extension b is severed from the end of the section 0, and does not form a part of the piping scroll, but stands up at the side and permits the goods to pass from the end of the hemmerscroll D onto the bottom plate of said pipingscroll. The portion a, bent upward as shown, becomes a side guide and keeps the goods in order. The transverse lip is bent slightly inward and over the hemmer. so as to bring the eye b over the line on which the stitching will be done. This lip serves as a side guide for use in putting on lace or for edge-stitching goods. The eye b can be made through the top of the hemmer-scroll D, as shown at g, Fig.1,instead of through the end of the tongue b but I prefer to make it through the latter, as shown, as thereby it brings it closer to the needle, and less skill is'required to manipulate the braid that is passed through it.

On the top of the hemmer-scroll, and near a narrow plate of metal, bent in the form shown, and adaptedto fold the edge of the piece of goods passed through it.

e is a corder fixed on the upper side of the projection b, as shown, and is arranged to hold and conduct a cord into proper position to be sewed to the goods that are passing through my device. It is so arranged with reference to the piping-scroll that-the functions of the latter are not interfered with.

form a so that the scrolls will be over the folder a and bring the latter in the same vertical plane with the folder d, guide b and lip 0 The bed-plate is soldered or otherwise made fast to the platform M.

The operation of the device will be plain to those accustomed to the use of sewing-machine attachments. Braid is fed through the eye b one piece of the goods is passed through the hemmer-scroll D, another piece is carried under the piping-scroll on the top of the bedplate, the piping is put through the pipingscroll, a piece of lace or other desired fabric is conveyed through the folder d and under the guide I) and below the braid, while an under facing for the seam is taken through the folder a below the bed-plate. If the piping used be too wide to pass freely through the pipingscroll, it may be taken out at the opening b and conveyed thence under the said scroll to the needle; or if two pieces of piping are to be extension I) together form a series of descendv The bed-plate E is-placed on the raised platthe larger end, Iplace a folder, d, composed of I00 sewed in the goods; one piece is taken out'at opening b while the other passes out at the exit end of the scroll. I do not deem it necessary to describe any of the particular kinds of work which may be done by my improvements. The variety is great, and will readily suggest themselves to any intelligent operator.

It will be seen,further, that when the blank is folded, as hereinbefore described, the projection 1) extends upward and forms a side guide or shield, 0", which acts to carry the goodsstraightforward. Itwillalsobeseeuthat the exit end of the device is sloped downward, so as to allow it to pass as far as possible under the presser-foot, and thereby shorten the distance the goods must travel to reach th needle.

The extension or table b serves as a support for the corder e and as a means to facilitate at the outset the putting of the piping into the taping-scroll. I have shown in Fig. 1 a piece of piping as it is being put into the scroll. The piping is first slipped under the scroll, with the end f extended to the left across the bed-plate, as shown. The other end,f, is then turned up over the table I), and is held firmly in this position. The end f is now carried along the bed-plate to the exit end of the device, and isdrawn under the scroll, and then the piping, by aslight drawing movement, is drawn upward past the end of the bottom plate, 0, into the scroll.

- It will be further observed that the raised platform a is so formed as to provide a vertical guide, a". The use of this guide is to facilitate the sewing of lace to the under side of the hem. This guide has an incline corresponding to the incline given to the foot a",

and the bed-plate projects over the guide far enough for lace or other materials to pass readily forward and be sewed to the goods. The guide prevents the lace or. other material from being moved too far to the left, and thereby thrown out of its proper position.

When it is desired to sew a piece of lace or other fabric on the upper side of the hem, which lace, &c., should not be folded, it is not put through, but passes over the top of the folder at and under the guide 12 The eye g may be used for braiding goods passed through the scroll D. The eye 0 in the guide I) must be used for the braid when one of the articles to be sewed together is carried over the top of the said scroll D. I prefer to feed the braid through eye If, even when the goods are put through the scroll, for reasons as hereinbefore set forth.

It will be seen that the corder e is formed from a flap made on the side of the extension 11 The eye 6 is first formed, after which the flap is turned down under the extension I). The folding of the blank, as hereinbefore described, brings the corder into its proper position before the piping-scroll. I prefer to form the corder by cutting and folding the blank as set forth; but it may be formed in a separate piece, and afterward soldered or otherwise made fast to the extension I). I prefer also to make the corder from the wide 'flap bentover the top of the extension; but it will be understood that it could be made from a piece of suitable wire bent into proper form and soldered or otherwise made fast on the tdge of the end of said extension 12 Having thus described my invention, what I claim, and desire to secure by Letters Patent,
